dmesg with black screen
This dmesg shows ERROR during booting, and HDMI screen is black.
I then tried to reproduce on ASUS VS239HR, and I can reproduce, with less possibility (1/20). Still saw the ERROR on drm-intel-testing-2015-03-27 Dupe of #82551? Can you try that patch from that bug and see? Yes. It looks same. So mark as duplicate. I will verify after 82551 got fixed *** This bug has been marked as a duplicate of bug 82551 *** It's very easy when connect to ASUS PA238Q monitor. Close this one since the same issue is already covered in 82551. Closing old verified. |
